Embodiment
Below illustrate and be used to implement most preferred embodiment of the present invention.
Embodiment
At Fig. 1 to Fig. 6 the example that is generated as of figure warp thread picture is represented initial embodiment, show that at Fig. 7 the figure warp thread picture that obtains in the comparative example is with for referencial use.Fig. 1 represents to use the analogue means 2,4th of the video generation device of embodiment, and colour scanner is used in input, also can be digital camera, monochromatic scanner etc.The 6th, keyboard, the 7th, input pen also may instead be suitable input medias such as mouse, trace ball.The 8th, colour picture monitor, the knitting design data that is used to show resulting figure warp thread picture, generated maybe is modeled to this design data the image of knitted fabric, clothes etc.Color printer 10 is similarly exported figure warp thread picture, knitting design data, analog image etc.
Analogue means 2 links to each other with LAN by LAN interface 12, carries out the input and output of figure warp thread picture, knitting design data or analog image etc., similarly, carries out the input and output of figure warp thread picture, knitting design data, analog image etc. by disc driver 14.And replace obtaining the input picture of yarn, also can in the long-range scanning device, read in, and from inputs such as LAN interface 12, disc drivers 14 from colour scanner 4.
The 15th, image generating program is the program that generates figure warp thread picture etc., reads in analogue means 2 from disc driver 14, LAN interface 12 etc.Image generating program 15 comprises memory command 16, the color data X of yarn and image (X, the memory command 19 D) of the memory command 17 of opacity D, the explosion command 18 of opacity D and the yarn that is generated etc. of the input picture of the yarn under 2 different background images such as white, black.Below with reference to the detailed content of the flowchart text image generating program 15 of Fig. 3.And, only background image is called background sometimes, the coloured image of yarn is called color data.
Be provided with the image production part 20 of yarn etc. as the part of analogue means 2, also can make colour scanner 4 grades and image production part 20 combinations and constitute independent video generation device.The 21st, the white background picture storage part is used for being stored in colour scanner 4 and for example closes cover cap, with white background input figure warp thread as the time input picture.Black background image storage part 22 is used for storage and for example opens cover cap at colour scanner 4, with black background input figure warp thread as the time input picture.At this, though the storage background is 2 white, black images, as long as 2 different images of storage background.
Color data calculating part 24 calculates the colour X of figure warp thread picture, and opacity calculating portion 26 calculates the opacity D of figure warp thread picture.The dynamic range of the 27 couples of D in extension is expanded, for example opacity D is more than 0 below 1, D value below first setting is converted to 0, the D value more than second setting is converted to 1, will be converted to 0～1 from the D value between first setting to the second setting.Also extension 27 can be set.Image storage part 28 is read the color data X of such generation and opacity D (expansion back) and is freely stored.
In an embodiment, color data X handles with the RGB system, also can handle with HVC system, Lab system etc., and opacity D finds the solution each composition of RGB, for example with their mean value as opacity D.Be under the situation of HVC system in addition, the V value shows lightness, in this case, as long as use the V value to calculate opacity D.
Fig. 2 shows the input of the figure warp thread picture that uses colour scanner.Place yarn on the manuscript table glass of scanner etc., cover cap is closed fully, filoplume is defeated and dispersed to prevent yarn from being compressed by cover cap.Open cover cap then and scan, obtain the image of black background.Similarly, close cover cap when scanning, obtain the image of white background.Owing to make these 2 input pictures of black background and white background after overlapping the use, thereby preferably, between 2 times images input, yarn is not moved.And, thereby preferably, specify the scope that reads image with respect to scanner because necessary image is only around yarn.
The generating algorithm that shows images such as yarn at Fig. 3.Read input picture A under the black background from the black background image storage part, read input picture C under the white background from the white background picture storage part.Wherein, the value of establishing the picture black of background is B, and the value of white image is W.As mentioned above, A, B, C, W are the image under the RGB system, have 256 grades of gray scales of 0～255.And establishing opacity is D, and D is a monochrome image, and the increase and decrease degree is 256 grades.
The relation that has A=B+ (X-B) D between the coloured image X of black background image A, black background value B, yarn and the opacity D.Similarly, the relation that has C=W+ (X-W) D between white background picture C, white background value W, coloured image X and the opacity D.Described 2 formulas can be found the solution X and D.Can show D by enough X, for example
D＝(A-B)/(X-B)＝(C-W)/(X-W) (3)
Or, can show as by obtaining the poor of A and C
A-C＝(B-W)-(B-W)D (4)
When thus D being found the solution, become
D＝{(A+W)-(B+C)}/(W-B) (5)
And can pass through
X＝{W(A-B)-B(C-W)}/{(A-B)-(C-W) (6)
Obtain X.The solution of simultaneous 1 power formula that is used to obtain D, X is any, not necessarily will solve tight numerical solution, also can only obtain approximate solution.
Then in order input picture is handled, thereby obtained the value of X and D with each pixel.Take out 1 pixel, obtain the value of X and the value of D as described above, carry out repeatedly finishing up to the processing of whole pixels.To have ignored color data X in the above description be the data conditions of RGB system, thereupon for opacity D, the situation of also ignoring the value DR that exist to use the R image to obtain, using the DG that the G image obtains and use the value DB that the B image obtains, the composition of color data X is these 3 of XR, XG, XB, and opacity D is the average of DR, DG, DB.On average having used arithmetic mean, also can be geometric mean, and it is average also can to use median (median) etc. to replace.
Be roughly in the D value under 0 the situation, promptly under the value of the value of A+W and the B+C situation about equally, can think in this pixel, not have yarn, and background image occur.Thereby be roughly in the D value under 0 the situation, D and X are made as 0.Be not under 0 the situation in the D value, the scope of establishing the D value for example is under the situation below 40/255 more than 0 below 1, and D and X are made as 0.Under D is situation more than 210/255, D is made as 1, the X value does not change.Be that the range expansion of D becomes 0～1 under 40/255～210/255 the situation in the D value.As described above whole pixels of input picture are handled, and storage figure warp thread picture (X, D).
The processing when input picture A, C obtain color data X, opacity D, for example also can in (6) formula, obtain the denominator of color data X earlier, its value roughly when 0 equates, also can be made as 0 with opacity D, color data X, is not that D and X are obtained in 0 zone about D.Perhaps also can at first obtain opacity D, obtain color data X in (6) formula then in (5) formula.And individual element is obtained D and X, and perhaps at first entire image being obtained opacity D, then to obtain X etc. be arbitrarily.
Fig. 4 shows the expansion of opacity D, the D value as first setting value as the situation below 40/255 under, the D value is made as 0.The D value as second setting value as the situation more than 210/255 under, the D value is made as 1.Dynamic range to D is expanded, so that remaining D value 40/255～210/255 becomes 0～1.Value after Fig. 4 D ' shows expansion.
In the D value is that transparency is higher under the situation below 40/255, thinks the influence etc. of the light of the deviation of irregular, each input of background image, the yarn scattering from the scanner, rather than has yarn in this pixel.Thereby the D value is to be made as 0 below 40/255.Under the D value is situation more than 210/255, consider the deviation of input, in order not compress yarn, and document board between keep some gaps and close the entanglement etc. of the input that cover cap etc. causes.Therefore, similarly, the D value more than 210/255 is made as 1.
In order to compare, only use white background picture to generate the figure warp thread picture.In the generation of the figure warp thread picture in comparative example, background image is made as white 1 look, the value of input picture is provided with the mask (mask) of opacity D from the part that the value of background begins to change as the figure warp thread picture, and cuts out the coloured image X of yarn.Opacity D approaches 0 in color data X value during near background image, approaches 1 when the difference of color data X and background image increases.But owing to do not obtain real figure warp thread picture with this algorithm, thereby using stencil is manually proofreaied and correct the image of opacity, thus obtain real as far as possible figure warp thread picture.
Show the figure warp thread picture that is generated at Fig. 5.51 of right side is the figure warp thread pictures that generate in an embodiment, the 52nd, show the figure of this figure warp thread picture with black background, and the 53rd, the figure that shows with white image.54 are to use the analog image of the knitted fabric of the figure warp thread picture that generates in an embodiment.The figure warp thread that shows comparative example in the left side of Fig. 5 is as 55, and it is to use white background to generate as described above.The 56th, the figure warp thread picture of comparative example and black background is synthetic and show, the 57th, show the figure warp thread picture of comparative example with white background.58 are to use the analog image of knitted fabric of the figure warp thread picture of comparative example.Wherein, figure warp thread uses identical yarn with figure warp thread as 55 as 51, and imports in same position.
Comparison yarns line image 51 and figure warp thread are as 55, and it is more that side's filoplume of embodiment shows, and becomes the image that turns white in comparative example.In background is the part of black when seeing, in comparative example, the part as white stripes occurs in the both sides of yarn, and this is formation figure warp thread picture because the white of the color data of Yarn filoplume and background colour is mixed.With respect to this, no matter the figure warp thread of embodiment is seen under black background as 51, still sees under white background, all is true true to nature, and filoplume is also abundant.Compare with analog image 54,58, in the image 54 of the figure warp thread picture that uses embodiment, filoplume is abundant, and shows the stereoscopic sensation of knitted fabric.With respect to this, in the image 58 of comparative example, knitted fabric is short of bright-coloured sense, feels thin no stereoscopic sensation.
Fig. 6 shows figure warp thread picture that uses another yarn and generate in an embodiment and the analog image 63,61st that uses this figure warp thread picture, the demonstration of figure warp thread picture under black background, the 62nd, the demonstration under white background.In order to carry out reference, show figure warp thread picture that uses white background and generate with comparative example and the analog image 73 that uses this figure warp thread picture at Fig. 7.The 71st, the black background demonstration of the figure warp thread picture that in comparative example, generates (under white background, generating), the 72nd, white background shows.The figure warp thread picture of comparative example turns white on the whole, and filoplume shows than actual thick.Compare analog image 63,73, very thin in an embodiment filoplume shows to such an extent that follow stereoscopic sensation, on the contrary, shows the filoplume thicker than reality in the analog image 73 of comparative example, and the shortage stereoscopic sensation is gone up in performance.
In an embodiment, can obtain following effect.
(1) uses 2 backgrounds such as white background and black background,, can generate the figure warp thread picture simply by read in the figure warp thread picture for 2 times in same position.
(2) in the figure warp thread picture that is generated, the color data of yarn, opacity are all true, can show yarn main body, filoplume in high quality.
(3) use resulting figure warp thread picture, when generating the analog image of knitted fabric etc., can show the tone of filoplume part, entire image realistically, thereby can correctly show the liquor style of knitted fabric.
In the above-described embodiments with the generation of figure warp thread picture as an example, in addition the present invention can also be used for the image relevant with transparent substances such as fibre, glassware such as clothes and generate.Under the situation of figure warp thread picture, its problem is for cutting out filoplume and background difference.And because the filoplume part is translucent, its problem is that background is not sneaked in the image of the filoplume that cuts out.Automatically cut out filoplume etc. and be difficult to the part that cuts out from background, and to remove background image about translucent part from the image of target object also be important for other fibres.Except clothes, for example also have curtain, woollen blanket, the tablecloth, seat cushion etc. in the fibre.And except fibre, the present invention can also be used for the generation that glassware, film, thin paper etc. have the image of transparent feel.Opacity D can be accessed in the present invention, the image X of the target object that goes out from background separation itself can be accessed simultaneously.The background image that imagination will be synthesized is F, and the image of object is X, when its opacity is D, can be by following (7) formula obtain composograph K.
K＝XD+F(1-D)＝F+(X-F)D (7)
The background of using is at least 2 kinds, preferred plain color background.And owing to imported in the captured image which partly for background, which partly be a target object, thereby preferably, for example manually imports background parts on a position.
For the clothes of dress such as manikin, furniture, household utensils, glassware etc., be difficult to change background and photographic images with scanner, for example make background become white and black and take with digital camera etc.Using digital camera under indoor situation of taking, if not good shooting environmental such as film studios, more be easy to generate the irregular of background owing to comparing with the situation of scanner, thereby in the extension process of opacity, preferably, make to compare with Fig. 4 a little and enlarge as the scope of D=0, D=1.
The image-related embodiment that shows the knitted garment of the mesh type of wearing at Fig. 8 to Figure 11 with manikin.Figure 10, Figure 11 are that to make background be image white or black and that take with digital camera.Fig. 9 is manually generated template and is cut out the image of clothes by Figure 11, with image white or that black background synthesizes.In the conventional example of Fig. 9, filoplume blackening artificially in white background.This is because owing to be difficult to only cut out the pixel that is equivalent to filoplume, and do not know opacity, thereby be mixed with black background image in the pixel of the filoplume that is cut out.Relative therewith, in the embodiment of Fig. 8,, can both obtain having the image of the filoplume of nature no matter background is made as white or black.
Under with the situation of image as object beyond the yarn, video generation device, program former state are used shown in Figure 1 getting final product, and the generating algorithm former state of image uses algorithm shown in Figure 3 to get final product.The image analyzer that replaces Fig. 2 uses the shooting based on digital camera etc. to get final product as described above.The record relevant with the embodiment of Fig. 1 to Fig. 7 also is directly applied for embodiment 2, embodiment 3.
Figure 12 to Figure 14 is an image of wearing the manikin of same garment, Figure 13, Figure 14 are the photographic images of the digital camera under white or the black background, Figure 12 figure that to be the image that will use Figure 13, Figure 14 and generate by embodiment synthesize with white or black background.Show the sleeve with transparent feel, the mesh of pants.Relative therewith, the image of Figure 13, Figure 14 former state, the bore portion of mesh are difficult to be separated into the image of clothes itself and the image of background.When therefore changing background, can become factitious image.
Embodiment 3
At image-related three embodiment of Figure 15 to Figure 18 demonstration with glassware.Figure 17, Figure 18 take the image of glass cylinder and water bottle with white or black background with digital camera.Thus, obtain the image X of glassware and the image of opacity D thereof by embodiment, the figure with the background image of desk, ashtray after synthetic be Figure 15, and the figure after synthesizing with white, black 2 background images is Figure 16.Owing to obtain the image of opacity D, even if thereby the change background also obtains the image (Figure 16) of nature, even and in the uneven image of the such background of the background with ashtray of Figure 15, also can access the image of nature, follow transparent feel to show surface gloss (Figure 15, Figure 16).
